摘要:
A sweetener concentrate containing sucralose and having improved thermal stability comprises particles of substantially non-crystalline sucralose dispersed evenly throughout, and adhering to, a water soluble oligosaccharide, the concentrate containing between about 20% and 80% sucralose on a dry weight basis. The oligosaccharide is preferably a glucose oligosaccharide such as maltodextrin. The concentrate can be prepared by forming a co-solution of the sucralose and oligosaccharide in water which is then dried. Other ingredients such as other high intensity sweeteners and flavorings may also be included.
摘要:
Crystalline sucralose having a mean particle size of at most 10 microns, the maximum particle size being no more than twice the mean, exhibits enhanced stability to heat. Preferably the sucralose has a mean particle size of at most 5 microns and a maximum particle size of at most 10 microns. A method of enhancing the thermal stability of crystalline sucralose comprises jet milling the sucralose to reduce the particle size, and render the size distribution such that the maximum size is no more than twice the mean.

摘要:
4,1',6'-trichloro-4,1',6'-trideoxygalactosucrose is prepared by a process including the steps of:(a) isomerizing 2,3,4,3',4'-penta-O-acetyl sucrose to 2,3,6,3',4'-penta-O-acetyl sucrose;(b) chlorinating the isomerized acetate at the 4,1' and 6'-positions; and(c) deacetylating the resulting chlorinated product; the isomerization step (a) being effected by treating a solution of 2,3,4,3',4'-penta-O-acetyl sucrose in an inert solvent with a weak acid at an elevated temperature.
摘要:
A fuel oil composition comprising a major amount of a fuel oil and a minor amount of a compound being the product of the 1,4-addition reaction of (i) ammonia, a primary or secondary hydrocarbyl-substituted amine or a mixture thereof to (ii) a species containing one or more α,β-unsaturated carbonyl groups, wherein the compound includes at least one hydrocarbyl group containing at least 10 carbon atoms. The fuel oil composition has improved low temperature properties.
摘要:
The invention relates to compositions and methods for prion degradation, decontamination or disinfection. The composition comprises an oxidizing agent, one or more proteases and a surfactant such as an ionic surfactant/detergent. The method comprises contacting a prion contaminated entity with a prion-degrading composition comprising an effective amount of an oxidizing agent, an effective amount of at least one protease, and an effective amount of a surfactant. The components of the composition may be contacted with a prion-contaminated entity sequentially or simultaneously using an aqueous composition. Typically at least two different proteases are used for optimal efficacy. Preferably the oxidizing agent comprises peracetyl ions or a source thereof. The invention also relates to kits comprising the various reagents.
摘要:
A fuel oil composition is disclosed. The fuel oil includes a major proportion of a fuel oil and minor amounts of: (a) at least one polar nitrogen compound effective as a wax anti-settling additive; and (b) at least one reaction product between a hydrocarbyl-substituted succinic acid or anhydride and hydrazine.
摘要:
The present invention provides for a pharmaceutical composition that includes tetrabenazine and a release-retarding agent; and a method of treating a hyperkinetic movement disorder (e.g., Huntington's disease, chorea associated with Huntington's disease, hemiballismus, senile chorea, tic disorders, tardive dyskinesia, myoclonlus, dystoniia and/or Tourette's syndrome). The method includes administering an effective amount of the pharmaceutical composition, for a period of time effective to treat the hyperkinetic movement disorder.
